Cactus / fissuratus

This grafted Ariocarpus fissuratus has been propagated from my own seeds.
I just had 1 fissuratus at that time and crossed with a fissuratus f Big Bend. The appearance of the plant is mixed, a standard fissuratus and a form Big Bend. I now have several standard fissuratus and am not necessary to cross with another forms.
This plant is in flower every year in this season.
